Currently running with a unlocked bb 9530(i think), and i have t-mobile. Well an hour ago i was making calls normal but i couldnt get pics messages. So i started messing around with the phone and next thing you know, my mobile network changed from t-mobile to verizon. and i am now unable to use my phone. cannot call text or anything. Can someone help me out here? Thank you.

Edit : Never mind i got it, but can someone help with with the mms? Is there a way to send pic messages without a data plan? i use to be able to until i got a bb.
